The Nokia Game was a series of Alternate Reality Games (ARGs) produced by Human-i Euro RSCG for Nokia. The concept was developed by Joost van Liemt and Sicco Beerda. Although mainly a competition through which Nokia promotes their latest phones, it is a true ARG which fuses various forms of mass media, promotes communication between players, and features involving storylines which change every year.

The original Nokia Game took place in 1999, and was only open to residents in the Netherlands. The 2005 edition was open to participants in more than 20 countries. Although notorious for the frequent bugs and crashes experienced during the Europe-wide live finals, the games were very popular. Nokia has not produced any games since the year of 2006.

The very first Nokia Game was only open to residents in the Netherlands, and centred round a young boy called Sisu, who is taken to hospital after a serious snowboarding accident. From there on it was up to the player to discover what had happened to him, and what to do next. It was a true Alternate Reality Game, with hidden clues in phone calls, magazines and TV adverts. Some sections even required players to phone each other to discover their usernames. Many games in this edition were also under a strict time limit, and failing the game once meant being instantly eliminated.

Following criticism of the previous game for being too hard, the 2000 edition not only allowed people from more countries to play, but was also more lenient during eliminations – players could usually practice games for as long as they liked, but could only "play" the games once.

The story centred on Sisu, a man taken into hospital after being poisoned in an ice cream parlour. Once conscious again, the player has to piece together what happened from clues left behind at the scene, eyewitnesses and a mysterious young boy called Mika, who claims to know a lot about Sisu and his past. The story was very mysterious, with many plot twists. Although future Nokia Games had a bigger audience, they lacked the secrecy and mystery present in the first two.

This Nokia Game was open to residents in the UK and most of mainland Europe. It was also the first game to be widely publicised on TV, radio, print and at live events.

The first contact with the game happened 2 weeks before the advertised start of the game, with pre-registered players receiving a phone call from the mysterious "Geneva", begging the player to watch a certain TV channel at a certain time. At the time given by Geneva, a television advert placed by Nokia was played. This explained the story so far: a strange blue light ("The Tone") has embedded itself in the bodies of a group of skateboarders, who have been found and captured by an unknown organisation. Only one boarder managed to escape. We learn her name is Alpha when, in the advert, she receives the same phone call all the players received previously. The address of the first challenge then appeared on the screen, warning players to complete the challenge before the 3-day deadline or risk dropping out of the game.

What followed was mainly a series of Internet-based Flash games, which tested abilities such as memorisation, note-making, decision-making, skill and research. One memorable section of the game, "Tunnel", involved a maze of tunnels which had to be navigated in real-time. In order to complete the game in time, many players had to wake up in the middle of the night in order to make their crucial last move before the deadline. Hints, important information, and phone numbers needed to progress in the game were featured as radio adverts, newspaper classified ads (featuring fake phone companies which were used to instantly transport the player to another area of the "Tunnel" maze), further TV adverts and even a full-page article on national newspapers (featuring a photo of Alpha, the player, with the caption, "Have You Seen This Woman?").
